m68k: atari: Add and use "atari.h" 

When building with W=1:

    arch/m68k/atari/time.c:59:1: warning: no previous prototype for ‘atari_sched_init’ [-Wmissing-prototypes]

       53 | void atari_mksound (unsigned int hz, unsigned int ticks)
	  |      ^~~~~~~~~~~~~

Fix this by introducing a new header file "atari.h" for holding the
prototypes of functions implemented in arch/m68k/atari/.
